Subject: [SPDK] NVME-CLI and Metadata


Hello, Everyone!I
have tried to test my SPDK app with the nvme-cli utility, as a part of test=
ing we need to pass metadata from nvme-cli to SPDK's BDev (it's my applicat=
ion). so for test we use:

nvme write /dev/nvme0n1 --start-block=3D0 --data-size=3D262656 --data=3D/de=
v/random --metadata=3Dmd --metadata-size=3D4

In driver I expect to see has been passed metadata in the field :bdev_io->u=
.bdev.md_buf
or
bdev_io->u.nvme_passthru.md_bufBut the both fields are NULL in the 'bdev_io=
' .

So, whatI'm need to check additionaly ?
TIA!
